Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention provides a method in which a table board is pulled upward from a storage position stored in a recess on the back surface of a seat and rotated to a nearly horizontal position. This invention relates to a pull-out table device that is used as a pull-out table device.

(Prior art) Such a pull-out table device extends vertically,
Consisting of a pair of frames arranged in a recess on the back of the seat back of the seat, and a table plate arranged between the frames so as to be slidable along opposing guide grooves formed in the frames. has been done. The table plate has guide pieces at the ends of the left and right sides, and the table plate moves by sliding the guide pieces in the guide grooves of the frame. The guide piece is usually a cylindrical pin.

used. The table board is then moved between a storage position, where it is stored in a recess on the back of the seat back, and a usage position, where it is pulled out to the top of the frame and then rotated and positioned almost horizontally. is placed on the table board in the use position.

As this type of table device, one with a fixed frame and one with a rotatable frame are known. For fixed type frames, there are
An example of this type of device is the table device disclosed in Japanese Utility Model Application No. 49-140301. In this known table device, the guide groove is formed so that the upper end is partially open and the lower side is narrow. One pin is implanted at the left side of the table board and at the lower end of the left side, respectively.

On the other hand, in a rotating type frame, the lower end of the frame is
At the back of the seat hack, for example, it is rotatably attached to the shaft of the seat back. In such a configuration, the upper part of the frame can be pivoted outwardly and removed from the recess. In order to ensure such operation, as shown in FIG. 15, the frame 512 is configured to integrally include a frame hinge portion 514 extending in a substantially horizontal direction at its upper end. Further, the guide groove 516 also includes a horizontal guide portion 520 formed in the frame hinge portion 514 in addition to a longitudinal guide portion 518 along the longitudinal direction of the frame 512. Then, the guide piece 5 of the table board 522
24 is formed from a pair of pins 526 and 527. In such a configuration, the table plate 522 is pulled up until the leading pin 527 reaches the connecting portion 519 between the longitudinal guide portion 518 of the guide groove and the horizontal guide portion 520,
It is then rotated and pulled out to a nearly horizontal use position. In the use position, the pin 526 is attached to the horizontal guide portion 5
At the tips of 20, other pins 527 are located in the connecting portions 519, respectively.

[Problems with conventional technology]

In order to prevent food and drinks from sliding or falling off the table board, the table board must be set approximately horizontally in the position of use.

However, in the frame-fixed type table device, the frame is fixed to the seat back, and the frame and table board move together with the seat back, as described above. Therefore, when the inclination angle of the seat back changes, the table board, which was previously set horizontal, also inclines as the seat back inclines, and is no longer maintained horizontally.

On the other hand, in a frame rotating type table device, the lower end of the frame is attached to a fixed member, such as the shaft of a seat back. Therefore, the table is maintained horizontally regardless of the inclination angle of the seat back.

In this way, the frame rotation type table device has the advantage of being able to maintain the table horizontally at all times, regardless of the inclination angle of the seat back. However, the table board is maintained horizontally by a pair of guide pins housed in a frame hinge portion at the upper end of the frame. Here, the larger the distance between the pair of guide pins, the more stably the table board can be horizontally supported. Therefore, each guide pin is arranged at a considerable distance apart, and the frame hinge portion is also formed with a considerable horizontal extension accordingly. Therefore, the frame hinge part.

When the table device is in the retracted position, it is not stored in the recess on the back of the seat back, and protrudes from the outer edge 530 of the recess, as shown in FIG. 15, which is unfavorable in appearance. Furthermore, the frame hinge portion protruding from the recess poses a problem from a safety standpoint.

Furthermore, a free slide system is adopted in which the guide piece of the table plate freely slides within the guide groove of the frame, and the sliding movement of the guide piece is not restricted even in the use position. Therefore, in the use position, the table board is in an unstable state with play between it and the frame. Therefore, if the table device user's knees or hands hit the tip or back of the table plate while in the use position, the table plate tends to easily rotate in the direction of the drawer position, and the use position is sufficiently Not guaranteed. Particularly when the table device is mounted on a passenger car, an airplane, a bus, etc., this backlash is undesirable because it causes vibration in the table plate at the position of use when the passenger car or the like is running.

[Purpose of the invention]

The object of the present invention is to provide a pull-out table device that suppresses rattling of the table board and can be stored without protruding into the recess on the back of the seat hack.

(Summary of the Invention) To achieve this object, according to the present invention, a table device is configured to include a hinge collar rotatably disposed at the upper end of a guide groove.

The hinge collar is formed with a notch into which the guide piece of the table board is fitted. Then, the biasing means is brought into contact with the hinge collar, and depending on the rotational position of the hinge collar,
The hinge collar is biased toward the table's use position or drawer position, thereby preventing play.

(Embodiments) Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.

As shown in FIG. 1, a pull-out table device 10 according to the present invention includes a pair of spaced apart frames 12 (only the left frame is shown in FIG. 1), and a table plate disposed between the frames. 14.

As can be seen from FIG. 2, the frame 12 has its lower end 12a rotatably attached to the shaft 18 of the seat back 16. When the table device 10 is not in use, the frame 12 is stored in a recess 20 formed on the back surface of the seat back 16 in the state shown at A in FIG. When using the table device 10, the frame 12
is rotated outward from the storage position A around the shaft 18 of the seat back.

Then, the table plate 14 is pulled out upward to a pull-out position B, and then rotated to a nearly horizontal use position C.

Note that the lower end portion 12a of the frame may be attached to a fixed member other than the shaft 18 of the seat back so as to be rotatable once.

As shown in FIG. 3, the table plate 14 is formed in a rectangular shape with a pair of guide pieces 22 at the rear end of the end surface.

In the embodiment, each guide piece 22 is formed from a single plate. However, each guide piece 22 may be formed from a pair of pins as in the conventional case.

Moreover, as can be clearly seen from FIG. 1, the frame 12 is
It is provided with a guide groove 24 in which the guide piece 22 of the table plate can slide. This guide groove 24 is formed only from a longitudinal guide part 26 extending in the longitudinal direction of the frame 12, and there is no horizontal guide part in the known structure. possible. In such a configuration, frame 1
2 has a compact structure without a horizontally extending portion at its upper end. Therefore, the table device 10 is
It is stored in the recess on the back of the seat back without protruding from the outer edge 21 of the recess 20 (see FIG. 2). Therefore, the appearance quality is not impaired, and the risk of the table device user colliding with the protrusion of the table device 10 is reduced, which is preferable from a safety standpoint.

As can be clearly seen from FIG. 4 in addition to FIG. 1, the hinge collar 28 is formed into a stepped cylindrical shape as a whole. A notch 30 into which the guide piece 22 of the table plate can be fitted is formed approximately in the center of the hinge collar 28, and this notch extends through the hinge collar 28 in the axial direction. The small diameter portion 32 of the hinge collar has a boss 36 around the notch 30 that extends to the outer edge of the large diameter portion 34 . Also,
The hinge collar 28 includes a convex portion 38 integrally provided on the circumferential surface of the small diameter portion 32. As described below, the biasing means 40
It comes into contact with the convex portion 38 and applies a biasing force to the hinge collar.

The hinge collar 28 having the above structure is inserted into the upper end of the longitudinal guide portion 26 of the frame from the back side to the front side of the paper as shown in FIG. 1, and the large diameter portion 34 functions as a stopper to prevent it from falling off.

A biasing means 40 is disposed at the upper end of the frame 12 to apply a biasing force to the hinge collar 28.

The biasing means 40 comprises a leaf spring 42.

It has a corrugated surface 44 in the center and is formed into a shape corresponding to the shape of the upper front surface of the frame 12. The leaf spring has its waveform surface 44 coming into contact with the right side (lower surface) 38a or the left side (upper surface) 38b of the convex portion 38 of the hinge collar, and selectively applies biasing forces in two contradictory directions to the hinge collar. to act on.

As can be clearly seen from FIG. 5, the leaf spring 42 is
2, the upper end front surface of the frame is open and a recess 48 is formed adjacent to the opening 46. Then, the leaf spring 42 is inserted into the recess 4 such that the wavy surface 44 contacts the recess 38 of the elbow collar through the opening 46.
It is located within 8. Further, a cover 50 is disposed in the recess from the outside of the leaf spring. By screwing into the screws 52 or the threaded holes 54 of the frame through the through holes 53, the leaf springs 42, and the cover 50, the leaf springs and the cover are screwed into the frame through the through holes 53. 1
In detail, the shape of the upper end of the longitudinal guide section 26 attached to the shaft 2 is as shown in FIG.
．． 5960.51. Using these flat surfaces as appropriate, the use position A and the pull-out position MB of the table board are defined respectively. The flat surface 60 defines the mounting angle of the table plate 14 in the use position NC (see FIG. 2), and in the embodiment, the mounting angle of the table plate is configured to be adjustable. That is, a through screw hole 64 is formed from the top surface of the frame 12 to the flat surface 60,
An adjustment screw 56 is screwed into this screw hole. Therefore, by extending the screw 66 from the flat surface 60, the contact position between the tip of the screw and the guide piece 22 of the table plate can be changed, and thereby the angle of the use position of the table plate 14 can be finely adjusted. Further, in FIG. 2, when the table plate 14 is rotated counterclockwise from the use position C to the drawer position B, the boss 36 of the hinge collar comes into contact with the flat surface 59, thereby causing the notch 30, The guide piece 22 is stopped at a position parallel to the longitudinal guide portion 26.

In the embodiment, the use position C of the table plate 14 is set by an adjustment screw 66 extending from the flat part 60, and the guide piece 22 of the table plate is brought into contact with the flat surface 59 to set the drawer position. B is set. However, the configuration is not limited to this, and for example, boss 3
6 may be brought into contact with the flat surface 58, or the screw 52 may be extended from the flat surface 58, and a boss may be brought into contact with the screw to set the use position C. Alternatively, the pull-out position C may be set by bringing the guide piece 22 into contact with the flat surface 61.

In FIG. 81, which corresponds to the usage position C shown in FIG. are in contact. In such a configuration, the biasing force of leaf spring 42 acts to rotate hinge collar 28 clockwise about hinge collar center 01. Therefore, the guide piece 22 of the table plate rotates one clockwise direction integrally with the hinge collar 28, comes into contact with the lower end of the adjusting screw 55, and sets the table plate 14 at the use position C. In this configuration, the guide piece 22 integrated with the hinge collar is always in contact with the lower end of the adjusting screw 66 due to the biasing force of the leaf spring 42, the table plate I4 and the frame I
There is no room for play between 2Δ. Therefore, the table board 14 is fixedly maintained at the use position C, and even if the screen of the user of the table device hits the tip or back surface of the table board, it will not easily move toward the pull-out position MB. Further, even when the table device 10 is mounted on a seat of a passenger car or the like, the table plate at the use position C does not vibrate when the passenger car or the like is traveling. Therefore, food and drinks, etc. on the table board are prevented from sliding or falling off.

Further, when the table plate 14 is rotated from the use position C to the pull-out position B for storage, the hinge collar 28 is moved toward the center with the guide piece 22 against the biasing force of the leaf spring 42. It is rotated counterclockwise around 01. Here,
The hinge collar has a convex portion 38 that corresponds to the corrugated surface 4 of the leaf spring 42.
4, and when it passes the apex of the waveform surface, the left half of the waveform surface comes into contact with the right side surface 38a of the convex portion. Therefore, a biasing force is generated in the leaf spring 42 that causes the hinge collar 28 to rotate counterclockwise. That is, when the neutral &170 connecting the center 01 of the hinge collar and the vertex of the waveform surface 44 is crossed, the direction of action of the biasing force of the leaf spring 42 is reversed.

Therefore, as shown in FIG. 6, the hinge collar 28 is
The biasing force of the leaf spring 42 causes the boss 36 to rotate counterclockwise until it is pressed against the flat surface 59 of the frame. The notch 30.3 of the hinge collar and the guide piece 22 of the table plate are then aligned with the longitudinal guide groove 26, and the guide piece 22 can slide within the longitudinal guide groove.

Therefore, when the table plate 14 is pressed downward, the guide piece 22 slides downward within the longitudinal guide groove 26. Then, when the guide piece 22 moves down the longitudinal guide groove 25 to the lowest point, the table plate 14 is completely accommodated between both frames. Thereafter, by rotating the frame 12 and the table plate 14 in the direction of the seat pack 16, the table plate and the frame are stored in the storage position ff1A in the recess of the seat back (see FIG. 2).

In the above configuration, it is neutral! After 1t70, the hinge collar 28 is not caused by an artificial turning force, and the leaf spring 4
It rotates by the biasing force of 2. The hinge collar 28 is then automatically rotated until the boss 36 comes into contact with the flat surface 59 of the frame 12. Therefore, the pull-out position B of the table board 14 that can be stored between the frames is automatically set. Therefore, there is no difficulty in the storage operation, and the table board 14 can be quickly and easily stored between the frames.

The hinge collar 28 is reliably maintained pressed against the boss 36 or the flat surface 59 of the frame under the biasing force of the leaf spring 42, and no play occurs between the hinge collar and the frame. Therefore, even if it is in the retracted position, it is not affected by vibrations caused by the running of a passenger car or the like, and no noise is generated due to backlash. Further, they are aligned and waiting in the notch 30 of the hinge collar, the longitudinal guide groove 26, and the guide piece 22 of the table plate. Therefore, when the frame 12 is rotated outward and the table plate 14 is pulled upward, the guide piece 22 of the table plate is always fitted into the notch 30 of the hinge collar. Thereafter, by rotating the table plate 14, the horizontal use position MC of the table plate is set. In other words, there is no difficulty in operating the drawer, and the use position C of the table board can be quickly and easily set.

Although the pull-out table device of the present invention is optimally mounted on the back of a seat pack of a seat in a traveling vehicle such as a passenger car, airplane, or lotus, the present invention is not limited thereto. In other words, the pull-out table device of the present invention can be used as a seat for lecture halls, conference halls, classrooms, etc.
It can also be attached to seats that are not attached to the vehicle.

The shape of the leaf spring 42 is not limited to the illustrated shape, and may take various other shapes.

A pullout table device 110 according to a second embodiment is shown in FIGS. 7 and 8. The table device 110 has a leaf spring 142
Alternatively, the table device 10 is different from the plate spring 42 of the table device M10 in the above embodiment except for its end shape.
It has almost the same configuration. And table device 1
10, the same reference numerals are given to the same constituent members as those of the table device 10. Note that this point also applies to subsequent embodiments.

As can be clearly seen from FIG. 8, the table device 11-'0
The biasing means 40 has end portions 142a, 14 having a similar shape to the wall surface 12a of the frame 12 facing the hinge collar 28.
2b. Then, the leaf spring 142 changes from the normal state shown by the solid line to the side of the frame 12 (
9) and around the hinge collar 28 (see FIG. 7). Therefore, due to the biasing force of the leaf spring that tries to restore the normal state, the ends 142a, 1 of the leaf spring
42b is pressed and attached to the frame wall surface 12a, and the right half or left half of the corrugated surface 144 is
It is pressed against the left or right side surface of the convex portion 38 of the hinge collar 28 . Then, move the hinge collar 28 to position C.
1 or the biasing force biased toward the pull-out position B is
Acts on hinge collar 28.

As described above, in the configuration of this embodiment, the leaf spring 142 is fixedly disposed between the frame wall surface 12a and the hinge collar 28 by simply being inserted into the frame 12 from the side. Therefore, there is no need to use screws, and the leaf spring 1
42 can be installed quickly and easily. Furthermore, since no openings are formed on the top or front surface of the frame, which is most visible, it gives a visually clean impression, which is favorable in terms of appearance quality.

The pull-out table device 210 according to the third embodiment is installed in the first
11. This table device 210 differs from the table device 10 described above in that the shape of the leaf spring is different, and the convex portion of the hinge collar is formed of a screw.

In other words, as can be clearly seen from FIG. 11, the biasing means 40
is a leaf spring 2 having locking pieces 242a and 242b at both ends.
It is equipped with 42. Then, the leaf spring 242 is inserted into the frame 12 through the opening 46 at the upper end of the frame, from the normal state shown by the solid line to the inwardly bent and deformed state, as shown by the dashed line. . And the locking piece 242
a and 242b are respectively locked in a pair of locking holes 243 formed in the wall surface of the frame.

Further, in this embodiment, a screw hole 246 is bored in the center of the circumferential surface of the hinge collar 28, and a convex portion of the hinge collar is formed from a round head screw 238 screwed into the screw hole. . Here, it goes without saying that the leaf spring 242 is arranged so that its wavy surface 244 is pressed against the screw 238. Even in such a configuration, the right half or the left half of the wavy surface 244 of the leaf spring is pressed against the left or right side surface of the screw 238 due to the biasing force of the leaf spring trying to restore its normal state. be done. Therefore, a biasing force that biases the hinge collar 38 toward the use position C5 or the drawn-out position B acts on the hinge collar 28, respectively.

In the configuration of this embodiment, the leaf spring 242 is connected to the locking piece 242.
A, 242b are locked in the corresponding locking grooves 243 to be fixedly attached at a predetermined position. Therefore,
There is no need to use screws, and the installation of the leaf spring 242 is easy.
Quick and easy. Further, since the convex portion is formed separately from the hinge collar 28, the MIi configuration of the hinge collar is simplified. By changing the screwing position of the screw 238, the height of the convex portion is varied, thereby adjusting the biasing force of the leaf spring.

A pullout table device 310 according to another embodiment is shown in FIGS. 12 and 13. In this embodiment, the biasing means 242 includes an opening 346 (a first
(see Figure 4).

In other words, as can be clearly seen from FIG. 13, the leaf spring 342 is attached with the waveform surface 344 at the tip and the surface 351 at the rear end.
Each has its own. Also, the plate spring 342 is attached to surface 3.
Four through holes 353 are formed in the frame 51, and corresponding screw holes 355 (see FIG. 14) are formed in the back surface 349 of the frame.

The leaf spring 342 is bent inward and deformed from its normal state shown by the solid line to the state in which the waveform surface 344 at the tip is inserted into the frame 12 through the opening 346 on the back side of the frame, as shown by the dashed line. inserted into. Then, the screw 352 is inserted into the screw hole 355 of the frame through the through hole 355 of the leaf spring.
is screwed into the plate spring 342 to attach the leaf spring 342 in place. Here, the right half or the left half of the waveform surface 344 of the leaf spring 342 selectively abuts the right side and the left side of the outer end of the guide piece 22 . Therefore, in the use position C shown by the solid line in FIG. 13, the hinge collar 2
8 in the clockwise direction, and in the drawer position B indicated by the dashed dotted line, the biasing force that rotates the guide piece 22 in the counterclockwise direction is applied to the guide piece 22.
respectively act on the hinge collars.

In the above configuration, the opening is formed on the back side of the frame where it is difficult to see, and nothing is formed on the top or front side of the frame. Therefore, it is possible to obtain a table device 310 that gives a visually neat impression and is preferable in terms of appearance quality.

The above-mentioned embodiments are for illustrating the present invention, and are not intended to limit the present invention in the same way, and all modifications and modifications within the technical scope of the present invention are also included in the present invention. Needless to say. For example, instead of using a leaf spring, a compression spring may be placed behind a bent plate corresponding to the corrugated surface of the leaf spring to apply biasing forces in opposite directions to the hinge collar or guide piece. You can.

(Effects of the Invention) As described above, the frame has no horizontally extending portion at its upper end and is compactly constructed. Therefore,
The table device is stored in the recess without protruding from the outer edge of the recess on the back surface of the seat back. Therefore, the appearance quality is improved and the possibility that the user of the table device collides with the protrusion of the table device is reduced.

Further, the use position of the table device is set with the hinge collar being pressed against the frame by the biasing force of the leaf spring. Therefore, the table plate is maintained at the use position without any wobbling, and a stable use position is set where vibrations and the like do not occur. Then, if the table plate is rotated until it crosses the neutral line of the leaf spring, the biasing force on the leaf spring will cause
The hinge collar is pressed into another position on the frame and the slidable pull-out position of the table board to the frame is automatically set. Therefore, the table board can be stored quickly and easily.

Further, the hinge collar is pressed by the biasing force of the leaf spring to a position where the table plate can be slid onto the frame and is on standby. Therefore, there is no difficulty in pulling out the table plate from the storage position, and the use position can be quickly and easily set. Furthermore, even in the stored position, there is no play caused by the hinge collar.
